7 Claims. (Cl. 229-40) This invention relates to improvements in packaging cartons, including cartons desirable for packaging products such as sliced bacon and the like. The main objects of this invention are,

First, to provide a carton well adapted for packaging food products such, for example, as sliced bacon, which is of generally parallelogram contour viewed endwise and at the same time effectively resists load or crushing stresses.

Second, to provide a carton having these advantages which may be formed of a single cut and scored blank of container board of relatively light stock, and at the same time is strong and rigid when erected and may be repeatedly handled without distortion.

Objects relating to details and economies of the invention will appear from the descriptfon to follow. The invention is defined and pointed out in the claims.-

A preferred embodiment of the invention is illustrated in the accompanying drawing in which:

Fig. 1 is a front perspective view of an erected carton embodying our invention.

Fig. 2 is an end elevational viewwith a portion of the outer end wall member broken away to show structural details.

Fig. 3 is an enlarged vertical section on a line corresponding to line 33 of Fig. 2.

Fig. 4 is an enlarged fragmentary view on a line corresponding to line 44 of Fig. 1.

Fig. 5 is a plan view of the blank, the scoring thereof being indicated by dotted lines. The window opening in the blank is illustrated as provided with a transparent closure which is in practice separate from the body member of the blank.

In the accompanying drawing. we have illustrated our invention as embodied. in a carton particularly designed for the packaging of sliced bacon and the like in which the slices are arranged in an inclined relation. We have not illustrated any contents in the accompanying drawings as they form no part of our present invention and our carton is adapted for and desirable in the packaging of food products other than sliced bacon.

The embodiment of our invention illustrated comprises a bottom 1, front wall 2, inner rear wall member 3 adjustably connected to the bottom by the scores 4. The top 5 is hingedly connected to the upper edge of the front wall 2 by the hinges 6. The outer rear wall member 7 is hingedly connected to the top by the folding or hinging scores 8. The outer rear wall member 7 has a sealing flap 9 hingedly or foldably connected to the outer edge thereof by the score 10.

In the embodiment illustrated a window opening 11 is formed in the top and extends into the upper edge of the front wall, and as illustrated is provided with a transparent closure 12. The ends comprise the inner end wall members 13 of parallelogram contour which are hingedly connected to the ends of the bottom at 14. The inner end wall members and the front wall have inwardly foldable corner flaps 15 having folding scores 16 therein, said corner flaps being hingedly connected to the rear ends of the inner Wall members 13 and to the ends of the front wall by the folding scores 17.

The top 5 has outer end wall extensions 18 on its ends hingedly connected thereto at 19 and positionable on the outer side of the inner end wall member 13. inwardly foldable corner flaps 2% connect the rear ends of the outer end wall members to the ends of the outer rearwall member. These fold inwardly in the same manner as the corner flaps connecting ends of the front wall to the inner end wall members. The sealing flap 9 is desirably adhesively secured throughout the length thereof to the under side of the bottom, the adhesive however not being illustrated. The sealing flap 9 is provided with struts 21 on its ends which when the carton is erected are positioned between the inner end wall members 13 and the outer end wall members 18, as illustrated in Fig. 3. These struts when erected engage the top as is illustrated and are positioned to resist downthrust such as results from stacking a plurality of cartons or other load on the carton which would tend to collapse it as a result of its parallelogram shape. The inner end wall member 13 also resists such collapsing and the corner members coact to that end, but these struts add greatly to the strength of the carton.

While we have illustrated our invention as embodied in a carton of parallelogram section or shape, our invention may be embodied in rectangular cartons. The sealing flap lapped upon and secured to the bottom also acts as a reinforcing element to resist collapsing stresses and enables the use of lighter stock than would otherwise be practical.

We have illustrated and described our invention in a highly practical embodiment thereof. We have not attempted to illustrate or describe other embodiments or adaptations as we believe this disclosure will enable those skilled in the art to embody or adapt our invention as may be desired.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is:
